Frequently Asked Questions
Q: Is the PW901A fitted to any Embraer ERJ regional aircraft?

A: The PW901A is not fitted to any Embraer ERJ aircraft. It is a widebody APU designed exclusively for the Boeing 747-400. Embraer ERJ regional jets use different, smaller APU models suited to their aircraft type and power requirements.

A: Yes. The majority of aircraft using PW901A APUs in active service are Boeing 747-400 freighters operated by large cargo carriers. As passenger 747-400 retirements continue, cargo operators represent the primary active demand for this model. Aero-Shield Capital maintains direct inventory to support these operators.

A:

PW901A compatible aircraft include the Boeing 747-400, 747-400ER, and 747-400F freighter. The 747-8 uses the PW901C and is not compatible. Aero-Shield Capital carries PW901A inventory under part numbers 3910001-02 and 3910001-03 and can confirm fit for your specific aircraft serial number.

A: Incoming PW901A parts must include FAA/EASA Form 8130-3, full ATA 106 ownership trace, a non-incident statement, AD compliance status, LLP status with CSN and remaining life, and TSN, TSO, and CSO data. Aero-Shield Capital provides this complete package on every transaction.

A:

Before approving a PW901A parts supplier, confirm they hold ASA-100 accreditation, maintain documented counterfeit parts prevention protocols, and carry direct inventory rather than sourcing on demand. Aero-Shield Capital meets all of these standards and maintains PW901A inventory with full documentation available at rfq@aero-shield.com.
